Fix html parse problem.
Add info to activate under image node.
-----------------------------------------------------------------------------------------
If you use image module, and want to place google map to image node,
you need to write some html tag into text field like below;
<!-- <a href="http://your_host_name/path_to_file/file_name.jpg">some word</a></p> -->
Then the module can detect the file, and create the google map,
whenever the jpeg file has geotagged data.
